Link: Access Google Authenticator on the Desktop

No longer are you limited to using your smartphone to use Google’s two-step authentication. There are many apps that you can use easily on your desktop to help keep your accounts more secure.

Keep in mind, though, that using a two-step authenticator app is less secure on your computer. Anyone who has access to your desktop can get your security key and log into your account. But if you don’t own a smartphone, using a program on your computer is better than nothing.

To use any of these apps to secure your accounts, you need to make sure you go through the usual process to enable two-factor authentication on Google or activate any other services that need two-factor authentication. Instead of entering the key into a mobile app, all you do is to enter it on your desktop.
